Drsnirr, a i residing at San i'h y of Torn Green and ex-as, haveinvented certain new l lnmrovements in Resilientdeclare the following tohe s full. clear, and rect desription of the invention, siieh asothersskilled in the is which it eppertsins to make and use some,.ierence being had to and to tin let 'ters and i ce marked tiers on,which rorin :1 partihis speoiiics'ti n. This ini'enaion relates oimprovements in what termed reilient or spring wheels.

The mi; 18 engagesthe threaded surface 16 of the rods 5 of the folly '7 and is applied tothe clencher rim 8, clearly seen in Figs. :2 and 3.

The rubber or elastic tread 6* is suitably held or secured in positiontogether with the outer members or caps 2 of the shoes 2 by means ofbolts 22- passed through and effecting connection between the main orbody portions of the shoes and said cap members, the bolts themselvesbeing equipped with nut and cotter pin fastenings 23 and 24respectively, as seen particularly in Figs. 2 and 3. The bolts 22, itwill be noted, are received in transverse grooves 25 produced in therubber tread 6 at suitable intervals thereinfor the suitable retention,

' thereof, in effective position as will be seen lines as at 31 and overby reference to Fig 4.

Suitable non-skidding members 26 of roughened, ribbedf or corrugatedpieces of material, pr ferably of the shape indicated or shown,resuitably applied to the periphery of the wheel, the same beingpreferably constituted as shown and detachably secured by screws 27 toadditional members 28 applied or secured to the tread member 6, saidadditional members breaking joints with said non-skidding members andhaving lateral flanges 29 serving to guard the latter against lateraldisplacement, as would likely occur if said non-skidding members werenot guarded at those points.

In the modification as suggested by, F lg 7 a departure from thepreferred form or disclosure of the shoe is shown, wherein it will benoted that the stepped or reduced inner end portion of the shoe isencompassed or inclosed by extending 30 of the shoe inwardly alongconverging said end, the resultant lateral spaces 32 being filled inwith hard wood cores 33, thus reinforcing or strengthening the shoe atthat continuous stepping of the lateral portions of the shoe issubstituted by the use of a sep arate end inclosing member 433 havingits inner 'ends terminated into lateral flanges 3st through which areinserted screws '35 entering tlie cores or fillingfin pieces 33 forsuitably'assembling and aiding the retention of the latter in positionand which flanges rest upon the clencher rim. Also the separate endinclosing member 33 and that; portion 31 of the shoe 30 fittingthereover'- ,the surface of LettersfPatent is the lateral portions 1. Awheel of'the type described, includl' I fecting connection bet point.The

are suitably riveted or secured together as at 36.

As will be seen frdm Fig. 4 each outer mem= her 2% is connected to itsindividual member or section 28, which latter members or sections areresilient. This allows each individual member or shoe 2 andits-cooperating parts to move radially of the wheel without necessarilycommunicating its movement to the adjacent shoes 2. By means of thisconstruction the periphery or tread ofthe wheel is.-capa-ble ofconforming to the contour or the road in the samerrhanner as obtains inthe use of pneumatic tires; that is to say, the shock is taken andabsorbed directly at the point of contact by a sudden altering of thetread tr: conform to' the contour or irregularity of the road-way, sothat the wheel is not forced to climb up over small irregularities orobstaclesin the road-way as must ocpur in 'allz resilient wheels havinga rigid 'tr'e'ad or perlphery.

It is further observed that my invention which is from the very natureof its general constituent parts, puncture-proof eliminates, .9 aspreviously indicated, the use of the pneuiatic tire together withitsaccessories inluding the demountable rim; it is charac teristic forits load carryingv capacity, being durable and free from parts liable-tobe 5 come prematurely weakened and inefficient. In event, however, ofaspring becoming broken the Wheel will not at once he rena dered uselessandcause the turning over of the car or machine but will allow of thelatter being'driven to a convenient point for the repair or replacing ofthe brokenmem-r v ber. Also in the use of my invention-fit does awaywith the n'ecessityof loadingdown the car. with wheels and tires asusual against an emergency, while the car is PCS, sessed of adegree ofresiliency which will promote the comfort of its occupants and make iteasier for the running of the machine.

Having thus fully described the invention wha Iclaimlas new and desireto secure bying ahub, afelly and rim, and spokes of een the hub and.felly a resilient tire, tubular segments closely embracing said tire andfelly-and s extending beyond the same, meansefi'ecting connectionbetween the tire andlfelly,"said segments having radially slidablemovement upon the felly, independently of the tire, and additionalresilient members arranged upon said connecting means and allowing ofthe inwardly yielding movement of said segments and exerting an outwardthrust upon said segments during relaxation. r
